Adipose tissue, or body fat, is an essential class of connective tissue prominent throughout the body. Adipose tissue serves to regulate and maintain energy homeostasis within an organism, and is primarily composed of adipocytes, or fat cells [1]. These cells are classified into two distinct types: White Adipose Tissue (WAT) and Brown Adipose Tissue (BAT). WAT is an active endocrine organ whose function is to store energy and to regulate the activity of insulin, lipid metabolism and satiety. BAT is located in discrete pockets, contains a large number of mitochondria and undergoes thermogenesis, where heat is expelled as chemical energy [2]. This review mainly focuses on the impact of microRNAs on WAT-related adipogenesis.
